VAPORIZING DEVICE.

Specification of Letters Patent.

Patented May 10, 1910.

To all whom it may concern:

Be it known that we, ABBoT A. Low, MAURICE J. WOHL, and HARRY Hnnrznnne,citizens of the United States, and residents, respectively, ofHorseshoe, St. Lawrence county, State of New York, the city of New York,borough of Manhattan, county and State of New York, and of the city ofNew York, borou h of Brooklyn, county of Kings, and State New York, haveinvented certain new and useful Improvements in Vaporizin Devices, ofwhich the following is a speci. cation.

This invention'relates to Vaporizers, applicable more particularly inconnection with the carburetion of fuel for oil or kerosene engines.

t constitutes a development of the type of vaporizer in which the oilimpinges or sprays upon a vaporizing surface heated by electricalresistance elements, preferably in the nature of bare wire coils, andthe ob eots are to prevent loss of oil by spattering, to distribute theoil over the heating surface, to insure the retention of the oil uponthe heating surface or in proximity to the elecmeans andinstrumentalities for accomplishtrical resistance elements untilcomplete vaporization is attained, and to provide an increased heatingarea.

The invention, therefore, consists in the ing these ends, as illustratedby this specification and the accompanying drawings and defined in theappended claims.

One phase of the invention may be said to consist in a vaporizing memberin the form of a trough having its bottom and sides wound withelectrical resistance wire, the sides serving to catch andvaporize anyoil spattering up from the bottonn Another'phase of the inventionrelates to the provision of distributing grooves or channels formed inthe vaporizing surface;

. and still another phase relates to the provision of a trap incommunication with these channels, for receiving any oil that passestherefrom unvaporized and holding the same until vaporization iscomplete.

In the accompanying drawings, Figure 1 is a side view, mainly invertical section, showing an embodiment or the invention, Fig. 2 is aplan-view of the vaporizing member, Fig. 3 is a transverse sectiontherethrough, and Fig. 4 is alongitudinal section.

Referring now to these views, the numeral 1 indicates the vaporizingchamber, of which 2 is the air inlet, and 3 is the passage through whichthe oil is sprayed into the chamber and through which the explosivemixture is drawn from the chamber into the cylinder of the engine. Thevaporizing member 4 may be mounted removably within the chamber 1 bybeing carried by the removable head and bottom member 5.

The vaporizing member i-may be said to be trough-shaped, possessing thebottom, preferably longitudinally inclined, member- 6, and the vertical,preferably triangular, side members 7. It is considered desirable tospace the side members 7 from the lateral edges of the bottom member 6,to leave the spaces or slots 9; and this may be accomplished by"providing the member 6, conveniently toward its ends, with lateral lugsor projections 10, to which the members 7 may be secured, as by screws11.

The members 6 and 7 are of insulating material (we have found slate adesirable material) and are wound, preferably transversely, withelectrical resistance wire 12, which is preferably bare and may be halfconcealed in thecgrooves 13. 14 indicates a cable carryingthe terminalsfrom the coils about the members 6 and 7.

The upper surface of the member 6 is preferably transversely arched, asshown in Fig. 3, and 'is provided with distributing channels or grooves15. \Nhile these channels maybe variously disposed, we prefer to formthem diagonally and intersecting. They are deeper than thewire-receiving grooves 13, and are therefore capable of carrying the oilimpinged upon the surface of the member (3 freely over said surface andbeneath the wires. These channels are shown following the curvature ofthe upper surface of the member 6, so as to deliver any unvaporized oilto the lateral marginal regions of the member 6. Here such unvaporizedoil is received in a trap, d sirably in the form of a comparatively wideand deep channel 16, extending in U-shape around the lateral and lowermarginal reg'ions of the upper surface of the member 6.

In operation, the oil that spatters up from the member 6 is-caught andvaporized by the side members 7 the channels 15 distribute the impingedoil over the surface of the member 6, thus hastenin vaporization; andthe trap 16 receives and holds until vaporized such oil as mightotherwise run off the member 6.

will be obvious that the particular form of construction illustratedneed not be adhered to, and that the several features of the inventionare susceptible to a considerable range of variation.

What we claim as new is:

1. A vaporizer for carburetion purposes, comprising avaporizing'chamber, and avaporizing member therein consisting of alongitudinally inclined bottom wound transversely with resistance wireand upright side members similarly wound.

2. A vaporizing member for carburetion purposes, comprising a bottomsection ro- .i ed with lateral projections, and upright side membersspaced from the lateral edges of said bottom member by said projections,bottom section and side members being wound with electrical resistanceWire.

vaporizing member for carburetion purposes, comprising an insulatingblock traversed by electrical resistance wire, said block being providedin its upper surface with oil-distributing channels.

t. A vaporizingmember for carburetion purposes, comprising an insulatingblock provided with electrical resistance wire, the oil receivingsurface of said block being travibting channels.

A vaporizing member for carburetion purposes, comprising an insulatingblock by electrical resistance wire, said .d with a network ofintersecting oilblock being provided in its upper surface withoil-distributing channels and an oil trap with which said channelscommunicate.

(3. A vaporizing member for carburetion purposes, comprising anins'ulatin block traversed by electrical resistance wire, said blockbeing provided in its upper surface with a network of intersectingoil-distributing channels and an oil trap in the form of a comparativelywide and deep groove extending around the marginal regions of ,saidsurface and communicating with the ends of said channels.

7. A vaporizing member for carburetion purposes, comprising aninsulating block traversed by electrical resistance wire, said blockbeing provided in its upper surface with oil-distributing channels whichconduct the oil beneath the wires.

8. A-vaporizing member for carburetion purposes, comprising aninsulating block traversed by electrical resistance wire, said blockhaving its upper surface arched and provided with oil-distributingchannels and a marginal trap in the form of a comparatively wide anddeep groove communicating with said channels.
